I do have the habit of talking in plural form. The site was built by my wife and I together, but I built 100% of the models myself. I did work on this full time for over 2 years before recently starting a new job. Now, I've got the models to a place where it becomes very difficult to improve them. I used to be able to make huge progress in a week, now I can spend 100 hours trying different theories and may not end up with any progress. That can be frustrating, so I decided, the models are fantastic right now, the execution framework is very stable, I'm happy with how they are performing, I'm going to let them run.

As mentioned, I'm not rich (1.4M in bot, ~2M total net worth), a SWE job paying 400-600k is quite meaningful to me even with 40-60% returns on my portfolio for the time being, just as potential profits from this website (also perhaps in that range within a year or two?) are also meaningful. If the website fails to generate significant revenue, I may shut it down. Also, I enjoy working on satisfying things, and now that the models are mature and the website is mostly finished except minor details, I'm happy to have a team and a project for now :)

That's also a good call out on the scaling problems--another reason our models trade the SPX futures, literally the most liquid financial instrument in the world. By my slippage calculations, the models don't need significant scaling updates until at least 1B+ is being traded.
